description
These octal buffers and line drivers are designed
specifically to improve both the performance and
density of 3-state memory address drivers, clock
drivers, and bus-oriented receivers and
transmitters. Together with the SN54ABT241,
SN74ABT241A,
SN54ABT244,
and
SN74ABT244A, these devices provide the choice
of selected combinations of inverting and
noninverting outputs, symmetrical active-low
output-enable (OE) inputs, and complementary
OE and OE inputs.
The SN54ABT240 and SN74ABT240A are
organized as two 4-bit buffers/line drivers with
separate OE inputs. When OE is low, the devices
pass inverted data from the A inputs to the Y
outputs. When OE is high, the outputs are in the
high-impedance state.
